Final answer:
A calorimeter absorbs a certain amount of the heat released during a chemical or physical process. The statement is false.
Step-by-step explanation:
False. Any calorimeter absorbs a certain amount of the heat released during a chemical or physical process. When an exothermic reaction occurs, the heat produced by the reaction is absorbed by the calorimeter, increasing its temperature.
Similarly, when an endothermic reaction occurs, the heat required is absorbed from the calorimeter, causing its temperature to decrease.
The amount of heat absorbed or released by the calorimeter is equal in magnitude and opposite in sign to the amount of heat produced or consumed by the reaction.
